Abstract
The invention provides a composite copper mine collecting agent and a preparation method of the composite copper mine collecting agent. The composite copper mine collecting agent is prepared by sodium n-butyl-xanthate, sodium nonyl xanthate, diethylene glycol benzoate, triethyl citrate, sodium ethyl xanthate, diethyl disulfide sodium phosphate, ethionine ester, benzothiazolethiol and activating agent. The composite copper mine collecting agent not only contains the sodium n-butyl-xanthate with higher hydrophobic effect for the sulfide of copper in copper mine, but also contains the sodium nonyl xanthate with higher hydrophobic effect for the oxide of the copper in the copper mine. The composite copper mine collecting agent is better in flotation effect for the copper mine which contains more sulfide of the copper and less oxide of the copper.
Description
Technical field
The present invention relates to ore dressing field, particularly a kind of collecting agent for compound copper ore dressing and preparation method thereof.
Background technology
At present, China to select smelting copper mineral raw material be mainly chalcopyrite, vitreous copper, bornite, malachite etc.Press the selecting and smelting technology condition, Copper Ores is marked to three natural types with the ratio of cupric oxide and copper sulfide.Be sulfide ore, containing cupric oxide, be less than 10%; Oxidized ore, be greater than 30% containing cupric oxide; Mixed ore, containing cupric oxide 10%～30%.
The collecting agent that occupies leading position in current copper ore floatation technique is the floating agents such as xanthates, thiophosphate and mercaptan, thiamines ester, xanthate, black powder ester, xanthate, but in actual ore dressing, the many requirements that can not reach design of result, copper, sulphur content are from undesirable, in the copper concentrate product, sulfur-bearing exceeds standard, the copper concentrate rate of recovery is on the low side, causes the waste of mining deposits.
Summary of the invention
The purpose of this invention is to provide a kind of compound copper ore collecting agent and preparation method thereof, the stronger sodium n-butyl-xanthate of hydrophobic effect that the sulfide of copper in pair Copper Ores is not only arranged in composite collector, also have the nonyl sodium xanthogenate stronger to the oxide hydrophobic effect to copper in Copper Ores, a small amount of composition of sulfide that the present invention is copper to main a large amount of composition is that the Copper Ores flotation effect of oxide of copper is better.
Technical scheme of the present invention is as follows:
This compound copper ore collecting agent is made by the raw material of following weight portion (kilogram):
Sodium n-butyl-xanthate 14-17, nonyl sodium xanthogenate 8-10, Diethylene Glycol Dibenzoate 2-3, triethyl citrate 4-6, sodium ethyl xanthate 6-8, diethyldithioposphoric acid sodium 2-3, second sulphur ammoniacum 1-2, benzothiazole mercaptan 12-14, activator 4-5;
Described activator is made by the raw material of following weight portion (kilogram): soybean oil 12-15, sodium lignin sulfonate 2-3, silane resin acceptor kh-550 1-2, rosin acid polyoxyethylene ester 2-3, dimethicone 4-5, fumaric acid 2-3, EDTA5-8; Its preparation method is that soybean oil, sodium lignin sulfonate, silane resin acceptor kh-550, rosin acid polyoxyethylene ester are mixed, and is heated to 60-65 ℃, then adds dimethicone, stir after 20-30 minute, add again residual components, continue to stir 45-60 minute, obtain.
Other composition except activating agent is mixed, then add activator, stir 15-30 minute under 6000-8000 rev/min and get final product.
The a small amount of composition of sulfide that the present invention is copper to main a large amount of composition is that the Copper Ores flotation effect of oxide of copper is better.Be suitable for the flotation of copper-sulphide ores.
The specific embodiment
Compound copper ore collecting agent, made by the raw material of following weight portion (kilogram): sodium n-butyl-xanthate 15, nonyl sodium xanthogenate 9, Diethylene Glycol Dibenzoate 3, triethyl citrate 5, sodium ethyl xanthate 7, diethyldithioposphoric acid sodium 3, second sulphur ammoniacum 2, benzothiazole mercaptan 13, activator 5;
Prepare activator, at first prepare the raw material of following weight portion (kilogram): soybean oil 12, sodium lignin sulfonate 2, silane resin acceptor kh-550 1.5, rosin acid polyoxyethylene ester 2, dimethicone 4, fumaric acid 2, EDTA 7; Its preparation method is that soybean oil, sodium lignin sulfonate, silane resin acceptor kh-550, rosin acid polyoxyethylene ester are mixed, and is heated to 65 ℃, then adds dimethicone, after stirring 25 minutes, then adds residual components, continues to stir 50 minutes, obtains.
Other composition except activating agent is mixed, then add activator, stir 20 minutes under 7000 rev/mins and get final product.
The present invention is for the flotation of copper-sulphide ores, and result of the test: the copper productive rate reaches 3.5%, and copper grade reaches 15.8%, and copper recovery reaches 86.1%.Apparently higher than single xanthate flotation.
